Answer:
The answer choice is B
Step-by-step explanation:
In order for a function to work, the input value must go with only one output value, so the only one that work is b
First pear Second pear probability
green (3/7)---------green (2/6) (3/7)*(2/6) = 1/7
---------red (4/6) (3/7) *(4/6) = 2/7
red (4/7)-------------green (3/6) (4/7)*(3/6) = 2/7
-------------red (3/6) (4/7)*(3/6) = 2/7
-------------------------
1/7 + 2/7 + 2/7 + 2/7 = 1
The probailities that two are green are: 1/7
The probabilities that one is green and the other is red are:2 /7 + 2/7 = 4/7
The probabilities that two are red are: 2/7
Answer:
28
Step-by-step explanation:
So in order to get this answer you want to use the combination formula which is 
Now you want to use the numbers given to you in the problem which is ₈C₂ and plug those into the equation
so your going to have something looking like this 
now if you have a calculator nearby and you plug in ₈C₂ your going to get 28 which is the answer.
hope this somewhat helps.
A+b=6.1 ---(1)
a-b=1.6 ---(2)
(1)+(2); 2a=7.7
then a=3.85
so b=a-1.6 = 3.85-1.6 = 2.25
so that the two numbers are 2.25 and 3.85
First two are scalene last one is isosceles.
